MAINTENANCE
Engine Cooling Air intake
Check that the engine's cooling air intake is free from
leaves, grass, and dirt.

deteriorates, which can lead to engine damage.
The cooling air intakes rotates when the engine is

Throttle Cable
Check that the engine responds to throttle increases
and that a good engine speed is attained at full
throttle.
If doubts arise, contact the service workshop.
If adjustments are necessary, they can be made as
follows for the lower cable:
1. Loosen the clamping screw for the cable's outer
casing and move the throttle to the full throttle
position.
2. Check that the throttle cable is mounted in the
correct hole in the lower lever, see illustration.
3. Push the throttle cable's outer casting as far to the
right as possible and tighten the clamping screw.

Choke Cable
If the engine produces black smoke or is difficult
to start, this can be because the choke cable is
incorrectly adjusted (upper cable).
If doubts arise, contact the service workshop.
If adjustments are necessary, they can be made as
follows:
1. Loosen the clamping screw for the cable's outer
casing and push the choke control fully in.
2. Check that the choke cable is mounted in the
upper lever, see illustration. Push the choke
cable's outer casing as far to the left as possible
and tighten the clamping screw.
